hello
can you tell me about the sensitivity of PALC with a MS detector

what about HILIC

thank you

Hi,
ESI: A(PALC) < A(HILIC); A - "sensitivity"

Yes (ESI)

The difference is very high in some cases. See theory of ESI (etc.)

"Sensitivity" of analytical system (LC-MS etc.) depend on many factors (method of ionization, ms-parameters, lc-parameters...). Answer to the question is much more difficult for other methods of ionization.
